Welch OW-5M explained

The Welch OW-5M (along with the OW-6M, OW-7M and OW-8M) were a family of American two-seat light cabin monoplanes designed by Orin Welch based on his first cabin monoplane design, the ACA Falcon. Welch's goal was to design cheap and functional light aircraft. The aircraft is a strut-braced high-wing monoplane with an enclosed cabin with side-by-side seats for two. It is similar in appearance to the Aeronca C-3, save for the wing struts. It had a steerable tailwheel landing gear and a nose-mounted engine. The fuselage was constructed with fabric covered welded steel tubing with a triangular cross section. The controls were mounted overhead with an adjustable control wheel that could be positioned for either pilot. Welch developed their own low-pressure wheels and tires for suspension.^[1]

Welch aircraft were first built by Welch Aircraft Industries, then production moved to Wilkes Barre, Pennsylvania in 1940, with the first aircraft christened "The Wyoming Valley". Total production of all types was 55 aircraft, 35 of which were Continental powered OW-5M models.
